ecore_cocoa: NSRunLoop integration

ecore_cocoa: NSRunLoop integration

Summary: Get rid of the old NSApplicationLoad() which was aimed to be use with Carbon. Unless the NSRunLoop is strictly integrated to the ecore_main_loop() (where cocoa events would be checked when entering the ecore_main_loop) I think the poller is the only option left.
